Oh, relaxation, that elusive activity that is often talked about and rarely achieved in today’s world. We all know we have too much stress and need to reduce it, but the execution is so elusive! Most of us probably know that our cortisol levels may be off, but fixing this takes more that just a spa day or some deep breathing.

The good (or bad) news is that even if we wanted to “relax” and schedule time for that purpose (scheduled relaxation?) we might not be able to actually relax, at least not in the strictly physical sense. True relaxation goes much deeper than the dishes getting done and no children crying.

I learned this lesson the hard way when for years I tried to “power through” the tough newborn years. Over time, my cortisol levels became elevated at the wrong time of day and I suffered the consequences for years. Here’s what I wish I’d known…

Top Cortisol Myths

What Is Cortisol?

Many of us now understand that cortisol has ties to stress levels, aging, and belly fat. But, what is cortisol and how is it related to your health?

Cortisol is an adrenal hormone that manages your body’s daily rhythm. Think of it as your built-in coffee pot. You wake up in the morning because your adrenals just made a fresh batch of it. You fall asleep at night because they shut it off.

Besides just being awake or asleep, you’d be amazed at how much of the body is run on a 24-hour schedule. Regulation of fat, digestion, immunity, blood sugar regulation, hunger, mental focus, and upkeep on your skin, hair, and nails all are controlled by the rhythm of cortisol.

How Modern Life Alters Cortisol Levels

Before our modern way of life, we had lots of cues that kept our cortisol rhythms in sync. The most powerful were the bright bluish light of dawn and the orange light of sunset. Feeling cold at night was another cue as was having a larger meal in the evening. Today we have many fewer cues to correct our cortisol rhythm and many new factors that throw it off. These include:

  • sugars, especially fructose
  • emotional stressors
  • pollutants, including lead and plastic compounds
  • medications
  • insomnia
  • shift work
  • noise pollution

The Cortisol-Stress Connection

The good and the bad news is that cortisol is tied to many things besides just what we think of as mental stress. In today’s world, our bodies feel stress from all those sources in our environment and addressing them can help not just reduce the feeling of stress but improve our cortisol rhythms.

For me, this was a huge factor in regaining my health and has even helped my thyroid improve.

Research also shows poor cortisol rhythms may be contributing to some of the biggest health problems of our time. In fact, one study of British civil servants showed that bad cortisol rhythms killed more people than smoking, heart disease, diabetes, or obesity.

Never assume that sleep or stress levels are minor factors for health!

Symptoms of Cortisol Imbalance

Telltale signs that your cortisol balance may be off include:

  • sluggish in the morning (even with sufficient sleep)
  • tendency to want to sleep late
  • headaches
  • strong food cravings (especially for sugar and carbs, especially mid-morning and mid-afternoon)
  • low sex drive
  • weight gain around the abdomen
  • acne
  • depression
  • anxiety
  • increased energy after 6 p.m.
  • trouble winding down for bed (and a second wind of energy around 11 p.m.)

Of course these probably sound familiar and could overlap with other health issues, so if you want to know for sure, see a practitioner or get lab testing to confirm.

How I Improved My Cortisol Levels

The stress of life may be unavoidable, but bad cortisol patterns are not! When I first tested (here’s what I used), my cortisol patterns were exactly opposite of where they should be. My cortisol was low in the morning when it should be high, and high at night when it should naturally drop.

Steps as simple as timing my food strategically and being intentional with light exposure made a tremendous difference for me, and now my cortisol patterns are normal, my sleep is better, and I feel much less stressed, even though I’m still doing as much as I was (or more).

Food to Improve Cortisol Patterns

The body uses cortisol to rescue us from low blood sugar. This makes carbs a tool we can use to help regulate cortisol.

My doctor recommended that I start my day with 25-35 grams of protein and finish it with 20-50 grams of high-quality carbs from natural sources. Great options include paleo-friendly sources like sweet potatoes (yams), turnips, squash, beets, and rutabagas. Having them later in the day helps not only cortisol but a whole host of weight-regulating hormones like leptin, ghrelin, and adiponectin.

On a practical level, this means that breakfast for me is protein+ veggies and dinner is protein + healthy carbs like sweet potatoes or squash. (For anyone wondering, this can also fit with Bright Lines, I just choose high protein sources for breakfast and lunch like sardines, chicken, or lamb and make sure I get the healthy carbs at night. I essentially do the lunch plan at breakfast, the dinner plan at lunch, and the breakfast plan at dinner).

And research backs up my personal experience with cycling food to improve cortisol. In a study of 42 women with weight loss resistance, diet alone was shown to correct cortisol rhythm by over 50% in 30 days. The diet in the study used carb cycling and avoided fructose and indigestible proteins like gluten and soy.

How to Use Light to Balance Cortisol

Light also had a huge impact on my cortisol levels. I was skeptical at first but after dietary changes didn’t completely fix my levels, I tried the light changes and the results were dramatic. Here’s why…

High cortisol can cause weight gain but so can low cortisol or cortisol made at the wrong times. Light is often the cause of the cortisol at the wrong times. When we are exposed to blue light (phones, computers, TV etc.) after dark, the body is getting the message it is early afternoon and then produces cortisol and reduces melatonin. This is the opposite of what we should do at night to get an optimal night of sleep.

In the same way, when we spend a lot of time indoors and don’t get any bright outdoor light exposure during the day, our body never gets a clear signal of night and day.

Simple steps like getting one half-hour of sunlight within an hour of waking can help cortisol if it is too high or too low. If this is not possible during certain seasons, a light-box that generates 10,000 lux of light can work as a good substitute.

The three steps that made the biggest difference for me are:

  1. Getting bright sunlight or exposure to a lightbox within an hour of waking up (great for fighting SAD as well)
  2.  Avoiding blue light at night by wearing orange sunglasses if I was going to use electronics after dark.
  3. Having lamps with orange bulbs (such as salt lamps) in each room and turning those on instead of bright overhead lights after dark.

Addressing Environmental Stressors

Over time, I also addressed some of the other factors my body viewed as stress. These included environmental toxins, my sleep patterns, exercise, and my inability to say no. I found that light and food cycling were the critical factors for me, but these other changes helped me see continued improvement after I’d addressed the core problems with light and food.

Avoiding Environmental Toxins

This step goes along with the food step above, as unfortunately, our “food” supply can be a major source of unnecessary chemical exposure that the body views as stress. But we also encounter environmental stressors in the form of chemicals in toothpastes, personal care products, deodorants, medicines, and cleaning chemicals.

Our exposure to large amounts of plastic, especially plastics that have been heated in the microwave, can also cause a build-up of estrogenic compounds in the body and alter our hormones. If the body is in a state of stress, the liver and kidneys are also not functioning optimally, making toxin removal slow and ineffective.

I focused on:

Instead, I make my own (try it… you’ll save money too!):

If you don’t have time (or want) to take the DIY route, there are now plenty of awesome companies doing the world a favor and making health-conscious products (thanks I’m sure to the moms/consumers who demand them!).

I definitely did not make the changes above overnight, so a word of encouragement: any change is a good change! Be patient… and start with food and light!

(p.s…. In hopes it will help other moms walking the same path, I share everything I learned and all of my favorite recipes and products in this 5-Step Lifestyle Detox guide, available soon!)

Making Sleep a Priority

This is one of the most important steps in stress reduction, and the one we are worst at. Historically, the body is used to sleeping when it is dark and being awake when it is light. When we stay awake long after the sun has set and don’t get enough cumulative sleep, we interrupt the body’s natural time for restoration and removal of toxins. The optimal time for regeneration during sleep is roughly between 10 p.m. and 2 a.m. Many people don’t sleep during part or all of this time, causing a backup of toxins and hormones in the body.

The body also has a delicate balance of hormones and depends on serotonin and melatonin to regulate good sleep and alertness during the day. Lack of sleep or interrupted sleep can disrupt the balance of these hormones, making you groggy during the day and restless at night. Poor sleep can also (logically) lead to fatigue, brain fog, memory troubles, and additional stress on the body.

Things like earthing and using magnesium can help improve sleep quality and reduce stress while you sleep. I’ve also found that when I do have to work at night on the computer, using blue-blocking orange sunglasses can help keep proper melatonin levels and cortisol patterns. (See recommendations at the end of this post.)

But at the end of the day, we have to learn to prioritize sleep.

Learning to Say No

Another logical step that many of us are bad at (me especially) is saying “no.” I’m not just talking about saying no in a parenting sense (though that could be good too… I recommend “No, you may not eat that candy bar/happy meal/ding dong/fill in the blank”).

Many of us have a commitment list as long as our arms, and the stress level to prove it. It is wonderful to help out whenever we can, but make sure you make yourself a priority and realistically evaluate what you can handle while keeping stress low and quality family time high. (Confession: I am really bad at this step myself!)

Adrenal-Safe Exercise

Oddly enough, exercise is a type of stress. It can be really helpful in reducing stress in the body but it serves us best when it is challenging but not overwhelming. The biggest factors determining if it is good or bad include: how stable our adrenals are and how much exercise we are already used to.

My doctor explained that the most adrenal-friendly types of exercise are light exercises like stretching and pilates. Walking and swimming would also be good options. The least adrenal-friendly activities include triathlon training or back-to-back days of high-intensity interval training.

If you have an autoimmune imbalance (like I do) and want more advice about which type of exercise is best for your body, check out this podcast.

Up the Antioxidant-Rich Foods

Antioxidants can help counteract the damage done by free radicals and stress hormones in the body. I made a conscious effort to up my antioxidant consumption from real food sources. This meant lots of antioxidant-rich fruits and vegetables, but also natural sources of vitamin C and other antioxidants.

During my food/light experiment, I also noticed I felt better when supplementing with vitamin C.

Learning to Actually “Relax”

Many people are too tired after an exhausting day to engage their minds and prefer to “relax” by watching TV or some other form of electronic distraction. There are some theories about the sleep-disturbing ability of the blue light emitted by these electronics, but whether you believe them or not, all that time spent watching TV is time that our minds are actively disengaged. Studies repeatedly show that people who actively use their minds in activities like reading, puzzles, or learning languages/new hobbies are happier and less stressed.

Consider using your valuable time for an activity that improves your mind and reduces stress.

On the flip side of this coin, most people also don’t turn their minds off enough. Let your “relax” mean “relax” and don’t relax by watching TV or doing another activity that causes activity without engaging the mind. Take time to pray or meditate and try to focus on the positive aspects of your life and the things you are grateful for.

Bottom Line: Start Balancing Cortisol Today!

All in all, relaxation is easier said than done. Heck, I just gave you my own to-do list I had to use to learn to relax! But focusing on cortisol levels is a great way to reduce the physical impact of stress hormones on the body and improve sleep.

Here’s a quick recap of the steps you can take starting today, without spending a dime:

Start your day with:

  1. Bright light/sunlight in the morning
  2. Have high protein in the morning

Finish your day with:

  1. Limited light in the evening (no screens and dim the lights after 7 p.m., for example)
  2. Healthy carbs with dinner

    Great article, I’m saving it. I am trying to figure out my own cortisol weirdness currently. It’s been going on for awhile. Lately I wake up about 4:30 pm with high blood pressure and high heart rate and hissing sensation in my ears/head, after many years of too low bp/pots/low energy. I think my blood sugar is dysregulated at night, often get morning headaches. I will try the carbs with protein at night thing. I already eat a high protein breakfast.

    I second how powerful light is. I first read of the orange glasses in a published scientific study in bipolar patients, on a great website psycheducation.org. In fact he references a case report of one manic patient that did not respond to medication, becoming stable by staying in total darkness for a few days. That’s extreme but it worked. I have my orange glasses on my nightstand, I’ve been forgetting to use them. One winter I tried using very short sessions of a UV tanning bed for vitamin D and mood, and after a few weeks wasn’t sleeping well, talking fast, etc. Danger signs. The orange glasses around the clock for a couple days completely calmed my body down. Note my eyes were covered from the UV exposure. How weird is that. Orange glasses are so useful for resetting circadian rhythm.

    So thanks for the reminder and the recommendations of things to try.

    Hi! Thanks for the helpful article Katie. Could you clarify what you mean by fructose and if that includes fruit? Thanks!

    There has been one area that may dramatically alter cortisol levels that has not been mentioned and is critical to understanding your health. If you have sleep disordered breathing like hypopnea, obstructive sleep apnea or central apnea your body has mechanisms to save your life from these suffocation style events which, too verbose to mention here, involve cortisol being injected into the bloodstream for each event that is of considerable consequence to the body. The number of these events determines the severity of the consequences from the volume and frequency of the cortisol events. The solution is not necessarily CPSP or otherwise, however the starting point is to understand that these events occur when you are in a sleep phase that causes an unconscious state in the brain- so you are completely unaware that they are happening. Some of the key indicators that may point to suffocation events are as follows:
    clenching and tight or rope-like jaw muscles
    cracking or broken teeth, receding gums, missing teeth, worn teeth, acid-marked teeth
    enlarged tongue and/or impressions of your teeth showing on your relaxed tongue
    elongated uvula, wide uvula, inability to see the uvula when opening your mouth
    flared lower ribs on your chest, like ski jumps or overly wide
    tight or sore neck, shoulder and jaw muscles
    migraines
    narrow nasal openings, dark circles under eyes, narrow nose bridge and /or narrow face
    dry lower lip, dry mouth, waking with a sore throat, acid reflux,

    this list is incomplete but is a starting point. Accompanying symptoms commonly found are also hormone issues, mood issues, increased agitation, irritability and /or addictive tendencies. Waking exhausted, feeling tired or wiped out may or may not be present. Infertility, low estrogen or testosterone, poor sleep schedule regulation as well. These issues are not to be trifled with, they can dramatically alter the quality and duration of your life, the health your heart and your nervous system and with time can cause costly dental damage. In children the symptoms are similar, but often not as well observed. Falling asleep in the car is abnormal; messy moving hair, wrecked messy bed, tired, behavioral issues, attention issues, inability to listen, stunted growth… all point to sleep breathing issues.

    This article was very helpful,I will keep it so I can work on these ideas. Right now I am working on the Whole Thirty and exercise. I need to work on sleep and eating three healthy meals. I am not a mom,but am in the above VIP. Do you eat any sweets,or grains on occasion? I really enjoy your emails.

    Would love you to post a sample week menu of what you eat for lowering cortisol levels! My husband has been battling so many of these symptoms for years & has tried everything from eating paleo to keto to leaky gut diet but can’t lose the belly fat & some of the other symptoms of high cortisol. Interesting about the carbs at night – more details about your meals, drinks & snacks would be great!

    Great article. Thanks for giving a lot of detail and some of your own experiences. I’m planning to try your diet and light suggestions. How do you feel about melatonin supplements?

    I find that ashwaghanda root does a good job of replenishing my adrenal glands. After supplementing for a couple weeks, I suddenly could tolerate drinking way more coffee and continue to be able to months later.

    Relaxing is hard! I’ve learned to carve out the time to do so but often find that I end up being stressed throughout and feeling guilty that I’m not doing anything practical.

    The light and food connection is an interesting area. I hadn’t thought about that before and the association does make sense.

    Its counterintuitive, but relaxation definitely takes some effort!

    I’ve recently come to the conclusion that I’m not producing enough serotonin, and I think this has been a problem for much of my adult life. After some research, I’m more confused than ever but I ordered and began taking L-Tryptophan, mostly for mood, PMS, and PMS-related migraine prevention. The minimum recommended dose of 500 mg. was clearly too much for me, as I had a racing heart all night after the first dose. Since then I’ve been taking 250 mg. and my mood is much improved. I feel much calmer (and I’m a homeschooling mama of 6 kids, including three teenaged boys and two recently-adopted girls from Ethiopia!) and in control.
    Unfortunately, I had a raging migraine last night, and somehow I suspect the L-Tryptophan is the culprit. What do you know about the amino acid and the safety of taking it in capsule form? There’s much contradictory information out there!!

    Thanks in advance for any insight and advice!!

      This is a comment very late in the game, but I, too, took tryptophan to raise my serotonin/pms/migraines and it caused some of the worst mood swings I’ve ever had. I am usually willing to give non-pharmaceutical remedies a second chance, but not tryptophan. It was horrible, and I threw out the bottle. Some seem to have a better experience with 5-htp but I am not going to try it. I do wonder about the safety of taking such large doses of amino acids.

      Hi! Cutting out sugar (all forms) and flour (all forms) has almost eliminated my severe PMS symptoms and mood swings. I went on Bright Line Eating, a suggestion from Katie, to lose weight. However, the pms stuff being mostly resolved has been a tremendous benefit. Also, avoiding caffeine 🙂

    While I’ve been out of the military for over a year, my husband is still Active Duty. We were temporarily relocated near his hometown of Dallas. So while he is 4 hours away, I have been staying with his Parents for Jan-May, so that we can save money on rent; and I can actually get to know his parents. They bought an in home sauna, I love going outside to have my Quiet-time and then going in the sauna for extra sweat out of Toxins. All the while listening to relaxing music such as nature sounds or just spa-type music. While the waves from headphones may be bad- it is really doing wonders for my health to be able to relax. I especially do it just before bed- using a ‘calm.com’ setting to meditate and relax just before laying down, or if i get worked up about something!

    As a stay at home mom I think much of my stress is over commitment, lack of sleep due to waking kids and trying to have everything perfect all the time. I’m trying to get better about this and I’m realizing this is time I will never get back with my kids. I consider myself very blessed to be able to stay home and I don’t want to look back and remember cleaning all day long and never actually stopping to enjoy it.
